## Z Scores & Probability

When we look at a standard normal distribution, we see something like the below. Here, we have the mean at the highest point, the mean, median and mode on top…

## Stats Learning Path

Statistics This section will take you through an introduction to many statistical concepts which will support your learning through Analytics & ML. Visit Our Blog Statistical Sampling Before we get…

## Standard normal distributions

We’ve discussed normal distributions in previous articles & today, we’re going to talk about standard normal distributions. By standardising distributions, we can compare two different distributions directly. Remember, a normal…

## Normal distribution & the empirical rule

A normal distribution looks a little bit like the below. It’s where the mean, median and mode are on top of one another. Remember in a previous article, we discussed…

## Linear Regression

Linear regression provides a rule which enables us to make predictions of Y based on the X. Effectively, it fits a line of best fit to a scatter plot, where…

## Correlation

Tech target defines correlation as: “a statistical measure that indicates the extent to which two or more variables fluctuate together”. There are two major components to correlation: strength and type…

## Percentiles, quartiles and box plots

Percentiles are 100 equal groups into which a population can be divided according to the distribution of values. A percentile can be between 1 and 99 – whatever number you…

## Measures of variance

Variance is a key statistical topic. It lets us know how close to the mean the data is clustered. Consider, if 2 classes have a mean exam score of 40%;…

## Measures of central tendency

In this article, we’re going to cover the basic measures of central tendency. You’re probably familiar with mean, median and mode already, but it is work re-visiting them before continuing…
